Generalizing to an arbitrary function.

Postby sepoto » Fri Oct 25, 2013 10:57 pm




























. . . . .









In the two above snippets I am wondering how "b)" was arrived at. In the question both parts of the equation show a plus and at "b)" one of the signs has changed to a minus symbol. I'm really not sure what is meant by generalizing to an arbitrary function as I am being asked to do.

Thanks in advance...

I'd guess it's just a typo. The formula doesn't make sense without the "-", but it does make sense and it does work the other way.
